Empty Body
Empty Body is a Watcher common skill that gains 7 Block and exits your current stance for 1 energy. Like Empty Fist, the key synergy is with Calm stance: exiting Calm generates 2 energy, so Empty Body effectively becomes a 7-Block card that gains 1 net energy instead of costing energy. This makes it one of the most efficient blocking cards in the game when used from Calm, as it provides strong Block while also refueling your energy.
Empty Body is a cornerstone of Calm-cycling defensive Watcher builds. The classic loop is to enter Calm (via Prostrate or Tranquility), then use Empty Body to gain Block and exit Calm for 2 energy — net +1 energy and 7 Block for the play. Re-entering Calm and cycling again chains these turns into sustained defense and energy generation. Empty Body also serves as a Wrath exit when needed, stopping the double-damage liability. Upgraded, Empty Body gains 10 Block instead of 7, making the Calm exit substantially more defensive.
